10. PIDE (Portugal)
The PIDE, or International and State Defense Police, was the secret police of Portugal’s Estado Novo regime from 1945 to 1969. Operating under António de Oliveira Salazar, PIDE enforced strict control over public life, suppressing political opposition and dissent (via portugal.com). It played a significant role in the repression of colonial independence movements in Africa, including those in Angola and Mozambique. The agency’s methods included surveillance, infiltration, and torture, creating a climate of fear that stifled free expression. PIDE’s legacy remains a subject of historical controversy due to its human rights abuses and its role in maintaining the authoritarian regime.
